There are individual power connectors for each power supply. See Section 3.3, “Rear panel”
4.2.3. 10–30 V DC
There is not any internal power supply in this option, powering is the same as for standard RipEX2.
The supply must be capable of providing the required input for the projected RF output. The power
supply must be sufficiently stable so that voltage does not drop when switching from receive to transmit,
which takes less than 1.5 ms. To avoid radio channel interference, power supply must meet all relevant
EMC standards. Never install a power supply close to the antenna. Maximal supply cable length is 3
m, and recommended wire cross section 1.0 mm

4.2.4. 18–30 V DC
There are also two independent power supplies with 18 to 30 V DC input voltage, one for each RipEX2
unit; input conductors are isolated from the rest of the RipEX-HS and thus allows positive or negative
grounding. The electric strength is 4 kV AC / 1 min.
When positive grounding is used, neither device connected via RS232, USB, ETH can have negative
grounding! There are individual power connectors for each power supply. See
section 3.3, “Rear panel”
4.3. Grounding
The grounding screw on the rear panel has to be properly connected to the grounding point of the rack.
The minimal required copper conductor cross-section is 4 mm
